We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. We work on pipe & cable gaps, flats & HMOs and linear gaps, and common reasons people get in touch are fire stopping disturbed by later work and gaps where walls meet ceilings or slabs.
For holiday lets, converted business premises or a community building near Codicote Bottom, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

What the job involves on each surface
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach.
Why deal with it now?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Older cottages and farmhouses around Codicote Bottom can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Codicote Bottom
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
The most common problems we see are:
- Fire stopping disturbed by later work
- Old fire sealant that has split or come away
- Open joints along the top of partitions
- Unsealed gaps where pipes and cables go through a wall
For site and facilities teams at buildings such as Codicote Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

What fire rated sealant looks like in Codicote Bottom
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Parish Church of St Giles are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Welwyn North station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Flag any open gap you spot round a pipe or cable
- Include fire stopping when you schedule refits
- Keep photos of seals that will be hidden
- File the fire-stopping record where your assessor can find it
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
